<P>
<PRE>
<i>// non-named parameter version</i>
template&lt;typename Graph, typename PositionMap, typename Topology&gt;
void
random_graph_layout(const Graph&amp; g, PositionMap position_map,
                    const Topology&amp; space);
</PRE>

<P> This algorithm places the points of the graph at random
locations within a given space. </p>

<h3>Where Defined</h3>

<a href="../../../boost/graph/random_layout.hpp"><tt>boost/graph/random_layout.hpp</tt></a>

<h3>Parameters</h3>

IN: <tt>const Graph&amp; g</tt> 
<blockquote>
  The graph object on which the algorithm will be applied.
  The type <tt>Graph</tt> must be a model of 
  <a href="./VertexAndEdgeListGraph.html">Vertex And Edge List Graph</a>.
</blockquote>

IN/OUT: <tt>PositionMap position</tt>
<blockquote>
  The property map that stores the position of each vertex. The type
  <tt>PositionMap</tt> must be a model of <a
  href="../../property_map/doc/LvaluePropertyMap.html">Lvalue Property
  Map</a> such that the vertex descriptor type of <tt>Graph</tt> is
  convertible to its key type. Its value type must be
  <tt>Topology::point_type</tt>, representing the coordinates of the vertex.
</blockquote>

IN: <tt>const Topology&amp; space</tt>
<blockquote>
  The topology used to lay out the vertices.  This parameter describes both the
  size and shape of the layout area and provides a random number generator used
  to create random positions within the space.  Topologies are described in
  more detail (with a list of BGL-provided topologies) <a
  href="topology.html">in separate documentation</a>.
</blockquote>

<H3>Complexity</H3>
<P> The time complexity is <i>O(|V|)</i>.
